Abstract

A hidden image game piece and a method by which a hidden image game piece is produced. A first pattern of colored ink is deposited on a transparent or highly translucent substrate at 110-180 density, forming the image which is to be hidden. Then a second pattern of colored ink, of a different color than first pattern's ink, is deposited upon the substrate on top of the first pattern, at 90-170 density. When the game piece is flooded with additive light of the same color as the second pattern's ink, the previously concealed image, composed of the first pattern's ink, becomes perceptible. Because a transparent or highly translucent substrate is used for the game piece, and because the density of the ink application is controlled within specific ranges, this game piece may be used with a computer monitor, or with other low-intensity sources of additive light.

Claims

exact text as granted — not AI-modified
We claim: 
     
       1. A game piece with a hidden image comprising: a. a substrate, selected from a group consisting of transparent and translucent substrates; and   b. a first pattern of colored ink deposited upon said substrate at 110-180 density, to form an image; and   c. a second pattern of colored ink, of a different color than the ink of said first pattern, deposited upon the substrate at 90-170 density and upon a selected area;   d. wherein at least a portion of said second pattern of colored ink is deposited over at least a portion of the first pattern of colored ink;   e. a dull coating which is applied over at least a portion of the substrate after application of the second pattern of colored ink.   
     
     
       2. A game piece as claimed in claim 1, further comprising a dull coating which is applied over at least a portion of the substrate after application of the second pattern of colored ink. 
     
     
       3. A game piece as claimed in claim 2, further comprising a dull coating which is applied over at least a portion of the substrate after application of the second pattern of colored ink.
